People With No Names: The Undocumented # 97

I am sitting on my patio in Tucson, Arizona.  It is a beautiful sunny morning and I am watching the "workers",  (aka bees) pollinating my beautiful, Arizona Agriculturally inspected Meyer lemon tree.  Oh,  wait a hummingbird just swooped in...and dipped into the lemon blossoms.  Where do these beautiful little creatures come from?  Do they hop up from Mexico?  Are they American bees and birds?  Gosh I hope so.
